I tinkered around with the ports on the 361. Big difference in cutting performance.
I am tempted to tear it back down and leave off the base gasket to see what else I can get out of it.
I wish I had taken pictures of everything. I would get to working on it and when I was half done I would remember that I needed to take pictures.
Yeah when the jug bolts are all thats left to be done, kind of late.
I jumped in blind but with a pretty good understanding of what was going...
I have my 260 and recently modded 361 set very rich. In fact I pulled the plug on the 361 yesterday and it was closer to black.
The 260 is about right. A mild fourstroke sound when running.
I still believe the 361 has more power running a tad rich. But I don't want to foul plugs...
Maybe I should clarify. I followed the factory taper and just enlarged it, slightly as this is my first rodeo on chainsaw porting. I just sanded the intake side to smooth out the casting marks.
Make sure you feather the edges on the piston side. I even put a slight angle on mine.
SO the wider the port is the better. I enlarged mine all around, Better to bellow it out more?
